UPB airframe was identical to the KAI-1, but equipped as a three-seater for crew transition from trainer to bomber.

First prototype aircraft was tested May 11 to 18, 1935, (pilot B.B.Kudrin), second - July 23 to 26 (A.A.Ivanovskij). Trial conclusion was overall positive:

Aircraft was recomended as trainer for bomber crews. Batch of 25 machines was ordered - but never built.

Third UPB was built with retractable landing gear. It was flown, but trials program not completed.
